It all depends which Birdy model you take on, for eg Birdy x JK11 series are really fast, the Birdy R20 is also really fast. If you do not want to fold your bike at all, then it will be the Reach GT mini velo, it will ride exactly like a road bike with 20 inch wheels. If you like the idea of quick fold and unfold to use public transport and go into shopping malls etc + speed on roads, then the Birdy bikes will be your choice!
